Abstract: The invention generally relates to performing sandwich assays in droplets. In certain embodiments, the invention provides methods for detecting a target analyte that involve forming a compartmentalized portion of fluid including a portion of a sample suspected of containing a target analyte and a sample identifier, a first binding agent having a target identifier, and a second binding agent specific to the target analyte under conditions that produce a complex of the first and second binding agents with the target analyte, separating the complexes, and detecting the complexes, thereby detecting the target analyte.

Abstract: A system, including method and apparatus, for generating droplets suitable for droplet-based assays. The disclosed systems may include either one-piece or multi-piece droplet generation components configured to form sample-containing droplets by merging aqueous, sample-containing fluid with a background emulsion fluid such as oil, to form an emulsion of sample-containing droplets suspended in the background fluid. In some cases, the disclosed systems may include channels or other suitable mechanisms configured to transport the sample-containing droplets to an outlet region, so that subsequent assay steps may be performed.

Abstract: The invention provides methods for the detection of molecular targets by digital PCR (dPCR) with a blocker for non-target molecules. Each target is provided with a unique mixture of probes. The blocker binds to a non-target molecule and blocks it from contributing to fluorescence from partitions. Two or more colors of fluorescence intensity are read, and two colors of fluorescence intensity are plotted as a 2D plot. In the plot, different targets contribute well-resolved clusters. Each cluster in the plot essentially lies a long its own radius allowing for radial multiplexing. The use of a blocker selects against the detection of non-target molecules and improves the resolution of radial multiplexing, allowing multiple targets to be detected.

Abstract: The present invention relates in general to microscopy systems. In particular, the present invention relates to microscopes rendering digital images of samples, with the capability to digitally control the focus of the microscope system, and the software used to control the operation of the digital microscope system. Further, the present invention relates to a microscope structure that allows for compact and multi-functional use of a microscope, providing for light shielding and control with samples that require specific light wavelength characteristics, such as fluorescence, for detection and imaging. The microscope is adjustable, with a structure that can move along range(s) of motion and degree(s) of freedom to allow for ease of access to samples, shielding of samples, and manipulation of a display apparatus.

Abstract: Provided herein is a chromatography media composed of a porous solid substrate (such as a membrane, metal, or metallic alloy) that is coated with hydroxyapatite (IA). Also provided is a chromatography media comprising a HA-coated substrate and uses thereof. Thus this disclosure provides a chromatography media composed of a porous solid substrate (such as a membrane, metal, or metallic alloy) that is coated with I-IA. Also provided is a chromatography media comprising a HA-coated substrate and uses thereof. Methods of preparing the HA-coated substrate are also provided.
